Background technology
Fibre-reinforced plastics are made up of host material, and this host material has rigidity and in addition by embedding in host material
Fiber composition and described fiber there is furthermore provided tensile strength.Fibre-reinforced plastics are particularly useful for the component of high load capacity,
Described component however should be also the lightest.Because fiber does not the most have intensity, so fiber must be with as follows
Mode is orientated, i.e. it is the most consistent with corresponding load direction.In order to realize this purpose, fiber often must be with
Different directions is placed.Fibrous layer is the best with load and more accurately matches, then this component is the best.For by fiber reinforcement
Plastics composition component have many manufacture methods.But for the production of many numbers of packages, the most only in rotationally symmetrical or tabular or
The component of rope form is pressed by winding or plate or rope pressing exists the method that can use.
Manufacture hugely on the contrary, complexity, high-quality 3D structure only can expend, this is because required fibre forming
The foundation of part is difficult, slowly with expensive.The structure of high-quality utilizes endless fiber to manufacture mostly.In many sides
In method, fibre forming part is first according to the Components Shape of desired three-dimensional, and the most so-called pre-shape manufactures, described fibre forming
Part is made up of fiber mostly, and these fibers are often arranged with multiple-layer overlapped, in order to obtain the machine direction of necessity.And then,
Fiber preform then utilizes host material carry out moistening or smear, and is the most also pressed and is finally hardened.Both in order to manufacture
Fiber preform can use the forming tool corresponding to desired Components Shape for moistening and/or stiffened members again, fine
Dimension performing member or component are placed and/or are pressed on forming tool or in forming tool.
In order to make fiber preform have the enough shape stabilities for processing further, fibre forming part is provided with
A small amount of glue or binding agent, and such as by being dried or being fixed by heating and cooling after three-dimensional input.
Fibre forming part is manufactured by plane semi-finished product that are stacked and fixing previously fabricated and that connect in advance mostly.This
A little semi-finished product e.g. belts, textile, fabric or fleece (Vliese), line or yarn that many of which is single be the most interleaved,
Sew up or the profile of bonding one-tenth plane.That is, when fiber unwinds from coil or a ball of string, so-called endless is being used
Line is called it as during fiber.A large amount of lines the most simultaneously unwind from coil or a ball of string are referred to as wire harness or yarn.At this yarn
Can be made up of at most several ten thousand single lines, described single line is also referred to as filament.
As also in DE 10 2,008 011 658A1 known like that, it is necessary to single parts according to one cutting board
Cutting into from plane semi-finished product, described semi-finished product provide as coiled material mostly.Described single parts are then placed within forming tool
Go up and be connected with each other or press.DE 10 2,008 011 658A1 is shown through bonding equally or sews up and manufacture these and half become
The example of product.While it is true, substantial portion of manual operation often necessity.The section being made up of semi-finished product for utilization
Carry out the equipment of performing member of the one-dimensional bending that machine is simple to manufacture by known in DE 10 2,008 042 574A1, described preforming
Part is pre-stored in case and is then store on core.More complicated shape also can not manufacture on machine ground.
Place for manufacturing the fiber that another possibility is that automatization of the fiber preform for more complicated component.
The wire harness elongated at this or the band being made up of wire harness are guided on forming tool back and forth by fiber placement head part, and at this side by side
Ground and place overlappingly, press and fix.For more complicated component, the expensive robot character of fiber placement head part
Control be necessary.Even if in the case of being used in parallel two, three or even four fiber placement head parts, manufacturing speed
The slowest, this is because head generally has to through long path, and this is because described head is continuously with carefully
Long fibre bundle work.Additionally, fiber placement head part has long especially with complexity, the line of placement head for multiaxial motion
The sightline tracking device of coil.There is in flexible pipe the special this sightline tracking device (to stop the torsion of yarn) guiding sound
Such as shown in US 2008/0202691A1.
Summary of the invention
The task of the present invention is to create a kind of equipment for manufacturing fiber preform and method, thus more complicated,
The structure of high-quality can also more easily control realize automatically, in terms of shape and fibre orientation neatly, rapidly and honest and clean
Valency ground manufactures.
This task is solved by a kind of equipment for manufacturing fiber preform, and wherein this equipment has multiple for carrying
For multiple lines or the unwinding station of yarn, multiple grabber and at least one the first forming tool, these grabbers can distinguish online or
The top of yarn captures single or multiple lines or yarn, and the most each grabber can be on maximum position and the path taken between position
Move back and forth, and wherein said position of taking is arranged in online site of delivery and described in position of taking more connect than maximum position

Time in the line that forming tool is moved into tension or layer, line deflects and uniaxial stress from forming tool
Uncontrollably change.By regulation, uniaxial stress can be controlled during manufacture process and especially during throwing in.
This is important, because line or yarn do not allow overload, and the most should be the most not lax, in order to reach optimal component
Rigidity.On the contrary when using plane semi-finished product, fiber only can be laid the most unstressedly.Further, in order to then throw in
Time, say, that when forming tool immigration or move toward one another (Zusammenfahren), line has the length of tension, is placing
During fiber placement head part, line must be placed with accurately the ultra-long of measurement according to three-dimensionality, and this is ultra-long is ring or similar
Form.Can be cancelled the most necessary calculating placing web by regulation uniaxial stress, this calculating is the most complicated and consumes in time
